Observations of Lunar Zenith Distances and resulting determination of Long.—(concld.)

* Observations were also taken at Yarkand on three other nights, when the moon was so unfavorably situated that these have not been employed.

t Observations were made on another night at Kila Panjah, but it appeared from the resulting time computations that the chronometer employed had been going irregularly.
